    Already did. Hopefully I'll be receiving the PCM this week.

Or even easier just make the error message more descriptive along the lines of waiting longer. Had I known about the timers, well I can follow directions. Those who cannot will ask questions regardless.

    RISK81 -

    I feel confident your issue will be resolved with a diy cable.
    Guys, Thanks for investigating the READ issue. As of now I have placed an order for the Adafruit IC bridge USB-UART Module (PN_1528-2591-ND) and also the Adafruit FTDI Serial TTL-232 USB Cable (PN_1528-1644-ND) through Digi-Key. Once the units are received, I'll construct a basic temporary cable and terminate to the mentioned pins listed above and post the results regarding the read function after a 10 sec delay from key-on.

    If this checks-out I like the idea of terminating a permanent cable to the back-side of the ALDL connector at the specified pins with appropriate strain-relief for future flashing / data-logging.

    Thanks again for everyone looking into this matter.

    All systems go!! I have successfully downloaded my PCM tune without an error via EEHack. It was the adapter all along (thanks to everyone). First attempt was with the FTDI serial TTL-232 USB cable - no success... Second attempt was with the AdaFruit board (PN-P284B) and a dedicated OBD2 blank connector with pins 4 & 9. Thanks again to everyone! 20190513_204326.jpg

    Hello, and congrats on getting your communication fixed. I am curious what the difference was between what you were using verses the AdaFruit. I apologize if you already said, I must have missed it.
